Assisting Hand Assessment Certification Course

Presented by Assisting Hand Assessment
Date: October 25-27, 2007
Hosted by the Occupational Therapy Development Committee at Bloorview Kids Rehab

Course Outline
The Assisting Hand Assessment (AHA) is a hand function evaluation instrument.  The test was developed for use with children who have a functional limitation in one upper extremity.  It measures and describes how a child uses his/her affected hand (assisting hand) collaboratively with the non-affected hand in bimanual play.  The AHA can be used with children as young as 18 months and up to 12 years of age.

The AHA has the unique perspective of assessing how the child uses his/her two hands together, in a fun and engaging situation where using two hands is natural. It is the child’s spontaneous and normal way of handling objects when playing that is assessed, not their best capacity to grasp, release or manipulate objects when prompted to use their affected hand. This makes the AHA a measure of usual performance.

This 2.5-day training course is the first step in becoming a certified Assisting Hand Assessment rater.  The course teaches the Assisting Hand Assessment (English Research Version 4.3), and includes information about the test construct, testing procedure and scoring practice on a range of children from videos.  A manual with detailed scoring criteria and a computer based scoring form is provided.  The remainder of the certification process is done following the course.  Each participant is required to complete eight calibration cases with satisfactory results.  Five of the cases are distributed at the course and 3 will need to be self-produced AHA play sessions.  The cases are sent to the instructors for individual feedback and for final certification.
